Wow, a lot have changed since i last visited the forum until it took me about 30mins to figure out how to post a new thread
New view, new features and new moderators. Great!!!, but my only suggestion is the "post a new thread" should stand clear and big not embedded in a drop down arrow. otherwise great stuff.

Well, esp to the power electronics gurus, i'll like to know whether any of you guys have increased the capacity (current size) of a battery by just using transistors (BJT, MOSFET) or step-up current IC besides connecting more batteries in parallel.
I've been wondering if it's practically possible to increase the current capacity of a Ni MH 4V8, 5AH, 0.5C max AAA battery pack to say 10AH by only using power transistors, without connecting more batteries in parallel?
Basically, my setup is as follows; the battery will power about 3 power transistors connected in cascade whose output will be connected to ~10A load (0.5 Ohms) and if possible isolated from the battery ground (-ve).
It seems theoretically possible but have some of you old folks practically achieved that without compromising the manaufacturer specs and performance of the battery (any rechargeable battery).
Off cource, a PICAXE chip will do all the monitoring and control.
Thanks and please let know if more info is needed.
